I have a viewpager with at least 3 fragments. If the user inputs data into A, then B, then C and goes back to A that data is lost from A.
I think I read somewhere that this has to do with memory management and since fragments only connect to or store adjacent fragments it's killing A when I get too far away. However I wish to retain the life of each fragment even were I to have >3.
How can I tell the viewpager to never kill a fragment unless explicitly directed?

Using an OnPageChangeListener in your View Pager, you can detect which fragment is currently shown in the View Pager. You'll then need to check which fragment is shown and then call a method on that fragment's class to start any sounds for example that you don't want to start until the fragment is the fragment in view.
The Best Answer is. -Finally, you can disable it: view_pager. disableScroll(true); or enable it: view_pager. disableScroll(false);
ViewPager save Fragment in FragmentManager with particular tags, So We can get ViewPager's fragment by FragmentManager class by providing tag. And ViewPager provide tag to each fragment by following syntax : Fragment page = getSupportFragmentManager(). findFragmentByTag("android:switcher:" + R.
use
setOffscreenPageLimit(int limit) on the ViewPager object. "It sets the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state."
